Mixed blessing of the coming AR (augmented reality) adscape is that virtual ads projected into our eyeballs will be cheaper and more targeted/effective than meatspace billboards.
AR “metaverse” stuff did not take off on the last hype cycle, and even Apple's VR headset does not sell. If AR is “coming,” it is coming rather slowly.
AR is "coming" in the same way smartphones were coming for years (decades?). Then iPhone happened and the rest is history. Technology needs to reach a level where it becomes obviously useful (for AR - low weight, cool form, not tiring,...)
